Answer:
I KNOW THIS
In metaphase, chromosomes are lined up and each sister chromatid is attached to a spindle fiber. In anaphase, sister chromatids (now called chromosomes) are pulled toward opposite poles. In telophase, chromosomes arrive at opposite poles, and nuclear envelope material surrounds each set of chromosomes.
Explanation:
Answer: The correct answer is -
d) a dominant trait that depends on the presence of only one of many dominant alleles.
Glaucoma is an autosomal dominant trait, meaning that presence of single copy of the defective gene is enough to cause the disease.
It corresponds to a group of diseases, which cause damage in the optic nerve, leading to loss of vision and if not treated, it ultimately leads to blindness.
Thus, option D) is the right answer.
The best and most correct answer among the choices provided by your question is the first choice or letter A.

Most cells grow, perform the activities needed to survive, and divide to create new cells. These basic processes, known collectively as the cell cycle, are repeated throughout the life of a cell. Of the various parts of the cell cycle, the division portion is particularly important, because this is the point at which a cell passes its genetic information to its offspring cells. In many situations, division also ensures that new cells are available to replace the older cells within an organism whenever those cells die.
Prokaryotic cells, which include bacteria, undergo a type of cell division known as binary fission. This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. The outcome of binary fission is two new cells that are identical to the original cell.
